IBM introduced a new network Quality of Service (QoS) server in i5/OS V5. This server enables your iSeries to function as a QoS server or client, but not as a router. QoS allows you to establish network priority and bandwidth requirements for TCP/IP applications, allowing you to smooth out network traffic and ensure that traffic flow fits your organization's needs. For more information on i5 QoS, read the iSeries Quality of Service manual.
